What's discharge rate of s23?

[kwui]

Battery on my s23, discharges much faster if I limit it to max 80% charge (battery protection), then if I put it to charge to 100%.

I don't know if you noticed this, making whole, saving battery to 80%, useless idea, when you're losing 20% NOW, and battery discharges faster.

I've also noticed this on other devices as well.
Maybe, voltage it reports in, it thinks it's 80%, like 4.0V, but it's due to charger, while it needs to saturate, to go higher % more.

I've noticed this on Xiaomi as well.

why my s23, discharges 1% per hour (accubattery)
so overnight, in 00h-06h, it lost 5%.

It seems like a feature of phone.
I've checked some logdump via *#9900*# , and it says 586 cycles and 92% health.

I know I shouldn't worry about battery. But I always thought they will improve it after some time.

I'm surprised how they've put 3785 mAh battery in s23 (reporter na android).
whilst some cheap Xiaomi, have 5000 mAh. I've had cheap Xiaomi, and it wasted through night few % as well, it's just I didn't cared, and had % display off.

But funny thing, how durable Samsung batteries actually are. because I still have j3 (2016) phone, which sitted 0% discharged for few months at least, forgotten. And, I've charged it now, to 50%, and it holds charge very well.
And I also still have 12-13 years old Samsung pocket neo, with original battery. and phone was used very very much and abused mind you. and charge still hold after all this time.

maybe rendering all this worry futile when Samsung batteries, have good materials, and will hold, and won't instantly drop % and be instable. like sudden drop from 45% to 13%

I’d be happy with any phone that lost 5% overnight.

I’ll move this to the S23 forum, where others familiar with the device may be able to comment.

Just staying connected to the network will use up battery. 5% overnight is good.

Is it really reaching 80%? Rhetorical question. We could agree though that today's 80% is not same as 80% nearly 3 model years ago when the battery was fresh and new. Let's not forget that using this battery saver mode is not a guarantee of anything. There are still a lot of factors that go into battery health. Heat, cold, idle, use, how low it is allowed to drain, etc. What we could do is ask that this question be moved to the S23 threads and see if other users are using this method and maybe you and them could share screenshots of your battery usage to compare their battery life/health to yours. @Laura Knotek & @B. Diddy, move or no?

I don't know how well they work but there are more than a few battery health apps on the Play Store that you could use to test your battery. Speaking of, with your concern about battery life are you using any saver apps? Battery Saver, Data Saver, or what about Anti-virus or Anti-malware apps? A lot of times these Saver apps, end up costing users more than they save. This is because in order to work they have to run in the background so they are always using power, or they close apps and services on the device that the device then must restart and the back and forth again uses power that it wouldn't if just left to its own devices. Test what battery life is like with these disabled or even better uninstalled. Hard to use power if not even installed on the phone.

Personally, I tried using this feature but also abandoned it because 80% is not 100% and if I'm going to be out I'd rather not worry if I'm going to make it to a charger or my entire trip coming from a 20% deficit to begin with.

Most manufacturers don't give specs on discharge rate for batteries u seem to be doing ok with the capacity at 92%

 

[mustang7757]

What I've seen on my s25u and Fold 7 it charges faster to 80 then 90 or 100% setting.

I moved this to the S23 forum, as suggested by VidJunky.

kwui, do you have an actual comparison of rates of battery drainage when charging up to 100% vs 80%? In other words, how many % per hour does the battery drop in each situation? Just want to make sure that you're not perceiving a faster drain when starting at 80% simply because you're starting at a lower charge level (and therefore will obviously reach any arbitrary low threshold level faster).

I merged your similar threads, since they're essentially about the same thing.

About 1%/hour drain is pretty good -- think about it, that means 100 hours of standby, which is >4 days.
